如果是通过ajax渲染数据的，也是可以使用。但得在渲染完成后才能调用

采用 Mock.js模拟数据，然后用ajax请求渲染到form表单里面

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
    <link rel="stylesheet" href="t-Switch.css">
</head>
<body>
<form>

</form>
<script src="jquery.min.js"></script>
<script src="switch-button.js"></script>
<script src="mock.js"></script>

<script>
    var html = '';
    Mock.mock('/test/getData',{
        'lists|5': [{
            'id|+1': 1,
            'email': '@EMAIL'
        }]
    })
    $.ajax({
        url:'/test/getData',
    }).done(function (data,status,jqXHR) {
        var data = JSON.parse(data);

        data.lists.forEach(function(value,index){
            html += '<span class="switch switch-off" name="s_marketEnable" id="stwichBtn_'+  value.id+'"></span>';
        })
           $('form').html(html);
//            数据渲染完调用
//           $('form').children('.switch').switchButton({callback:callback});
           $('.switch').switchButton({callback:callback});
        });
//    回调函数
    function callback(dom) {
        var id = dom.attr('id');
        alert("id:" + id);
    }

</script>
</body>

</html>
